Publication number: 20240103618Abstract: Methods and apparatus for correcting the gaze direction and the origin (entrance pupil) in gaze tracking systems. During enrollment after an eye model is obtained, the pose of the eye when looking at a target prompt is determined. This information is used to estimate the true visual axis of the eye. The visual axis may then be used to correct the point of view (PoV) with respect to the display during use. If a clip-on lens is present, a corrected gaze axis may be calculated based on the known optical characteristics and pose of the clip-on lens. A clip-on corrected entrance pupil may then be estimated by firing two or more virtual rays through the clip-on lens to determine the intersection between the rays and the corrected gaze axis.Type: ApplicationFiled: September 19, 2023Publication date: March 28, 2024Applicant: Apple Inc.Inventors: Julia Benndorf, Qichao Fan, Julian K.

Publication number: 20240104958Abstract: Methods and apparatus for providing eye model matching in a device are disclosed. When a user activates a device and the presence of the user's eye is detected, an image of the user's eye is captured. An eye model matching process is then implemented to determine a stored eye model (e.g., an eye model stored after enrollment of the eye on the device) that best matches the eye in the captured image. Determination of the best matching eye model may be based on matching between properties of the user's eye in the captured image (such as cornea and pupil features) and properties of the user's eye determined by the eye model. The best matching eye model may then be implemented in, for example, an eye gaze tracking process. In certain instances, the best matching eye model satisfies a threshold for matching before being implemented in the downstream process.Type: ApplicationFiled: September 19, 2023Publication date: March 28, 2024Applicant: Apple Inc.Inventors: Hao Qin, Hua Gao, Tom Sengelaub, Jie Zhong

Publication number: 20240104967Abstract: A personalized eye model is used to generate synthetic gaze features at ground-truth eye poses Gg. Corresponding synthetic gaze poses Gs are estimated from the synthetic gaze features using an average eye model. A linear regression is applied between Gg and Gs to generate a gaze correction function. The gaze correction function represents differences between the synthetic gaze Gs of the subject eye at the display and that of the average eye model Gg at the display, but does not contain security- or privacy-sensitive information. Further, the personalized eye model cannot be recovered from the gaze correction function, and thus the gaze correction function can be stored unencrypted and available for use during a cold boot of a device prior to login. On a cold boot of the device, the gaze correction function may be accessed and used with an average eye model to improve gaze-based interactions.Type: ApplicationFiled: September 19, 2023Publication date: March 28, 2024Applicant: Apple Inc.Inventors: Rene Heideklang, Hua Gao, Hao Qin, Tom Sengelaub

Publication number: 20240105046Abstract: Systems and methods are disclosed to enable performance of a lens distance test in head-mounted displays (HMDs) to determine the distance between a user's eye and a lens of the HMD (e.g. the display lens in a virtual or augmented reality device). In embodiments, the HMD is configured to determine a current pose of the eye based on a series of captured eye images. The pose information is used to determine the distance from the apex of the cornea to a closest point on the lens. If the determined distance is too small or too large, an alert or notification is generated instructing to adjust the HMD or change the light seal to achieve better distancing, in order to reduce the risk of eye injury and/or improve user experience. In embodiments, the lens distance test may be repeated during a user session to reevaluate and/or monitor the lens distance.Type: ApplicationFiled: September 20, 2023Publication date: March 28, 2024Applicant: Apple Inc.Inventors: Chia-Yin Tsai, Kai Benjamin Quack, Hua Gao, Tom Sengelaub, Alper Yildirim
